Retrograde ejaculation is a known complication of bladder neck surgery. Revision of a bilharzial bladder neck obstruction accentuates the incidence of this complication. Some of the difficulties in the surgical correction of retrograde ejaculation are directly related to pathological changes caused by bilharziasis. In this study a new length of premontanal urethra is formed using the trigonal urothelium and the trigonal muscles with their intact sympathetic innervation to correct retrograde ejaculation following bladder neck surgery. Normal (antegrade) ejaculation was restored in four of five men using this procedure. The physiological basis of the procedure is discussed.
逆行射精是膀胱颈手术已知的一种并发症。血吸虫性膀胱颈梗阻的修复会增加这种并发症的发生率。逆行射精手术矫正中的一些困难与血吸虫病引起的病理变化直接相关。在本研究中，利用三角区尿路上皮和三角肌及其完整的交感神经支配形成一段新的肛门前尿道，以纠正膀胱颈手术后的逆行射精。采用该手术方法，五名男性中有四名恢复了正常（顺行）射精。本文讨论了该手术的生理基础。
